UNITED STATES PATENT NELSINE PEPPER DENOKLA, OF DENVER, COLORADO.

WORK-HOLDER.

SPECIFICATION forming part of Letters Patent No. 691,364, dated January21, 1902. Application filed March 14. 1901. Serial No. 51.147. (NomodelJ To all whom it may concern:

Be it known that I, NnLsINE PEPPER DENOKLA, a citizen of the UnitedStates of America, residing at Denver, in the county of Arapahoe andState of Colorado, have invented certain new and useful Improvements inSewing-Work Holders; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othcrsskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

My invention relates to a sewing-work-supporting device adapted to beattached to a persons leg for holding one end of fabrics while manuallysewing them; and the object of my invention is to provide a resilientclamping-rin g thata person can spring around the leg either above orbelow the knee and having secured to it a spring-controlledsewing-work-clamping vise. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure 1 is a sideelevation of my improved band-forming and sewing-worksupporting device.Fig. 2 is an end elevation of Fig. 1. Fig. 3 is a plan view of Fig. 1.Fig. 4: is an end view of the spring-clamping clasp, showing theopposite end view from that shown in Fig. 2; and Fig. 5 is a sectionthrough the fastening-button.

Similar figures of reference refer to similar parts throughout theseveral views.

Referring to the drawings, the numeral 1 designates a round fiat dividedring of resilient material, preferably steel. Its free ends 2 and 3 aremade blunt by curving them outward and backward from the periphery ofthe ring. To this ring at a point opposite its free rings I secure,preferably by riveting, a wedge-shaped fastening-button hwhich comprisesathin flat head portion 4a and a shank 4 The head of the button iswedgeshaped at its opposite side edges 4 To this wedge-button I securedetachably the lower jaw 5 of a clamping-vise 6. This jaw contains aT-shaped slot 7, having tapering or wedge-shaped sides 7 extendingacross the central portion of its under side, that is adapted to slideon the button at one side and fit tight on the button at the centralportion of the jaws width, and is thus quickly put on or taken off ofthe ring. This arrangement also enables me'to interchange thework-holding device for other devices-such, for instance, theband-forming device shown in my application Serial No. 32,02et.

The upper jaw 8 is pivotally attached to the lower jaw bya pivotal bolt8 A wedgeshaped space 9 is formed in one end of the jaws, in which aspring 10 is secured, and a recess 9 is formed in each jaw, which formsa clearance-space for the spring when the upper jaw is pressed againstthe lower one. One end of this spring bears on and is secured to thelower jaw, and the opposite end bears on and is secured to the upper jawand holds them constantly under resilient pressure apart, thus holdingthe opposite ends 11 and 12 of the jaws 5 and 8 forcibly together. Theseends are the cloth-clamping ends of the cloth-clamping device. Theopposing surfaces of these jaws may be fluted or serrated by flutes orcorrugations 13, although they may be left smooth, if desired.

The operation of the device is as follows: The spring-ring is preferablysprung over the leg of an operator, either above or below the knee, andthe jaws of the clamping-vise are sprung apart and one end of the workto be sewed on is placed and clamped between them, while the oppositeend of the work is held by the hand of the person doing the sewing.

My invention is simple, useful, and easily operated.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In a sewing-work-holding device, the combination of the springringhaving a wedge-shaped button at the central portion of its circumferencewith a pair of vise-jaws pivotally secured together having a springarranged at one of their ends to hold their opposite jaws together byits resilient tension and having the opposing surfaces of said jawscorrugated and a tapering T-shaped recess in the bottom of the lower jawarranged to slide over said button at its widest side and to fit tightupon it at its central portion, substantially as described.

2. In a sewing-work-holding device, the

combination of the spring-steel, open-ended said lower jaw and thespring arranged to 10 supporting-ring having a wedge-shaped and hold theupper and lower jaws normally to- .T- shaped fastening-button comprisingthe gether, substantially as described.
